REGISTERING ATTACHMENT FOR SEWING MACHINES.

Application filed February 28, 1921. Serial No. 448,593.

To all whom it may concern:

lie itknown that I, \VALTER L. HANxsz, a citizen of the United States,residing at Houston, in the county of Harris and State of Texas, haveinvented certain new and useful Improvements in a Registering Attachmentfor Sewing Machines, of which the following is a specification.

This invention relates to new and useful improvements in a registeringattachment for sewing machines.

One object of the invention is to provide an attachment of the characterdescribed designed to be attached to a sewing machine and which willregister the hemstitching done by the machine.

Another object is to provide an attachment of this character which willregister not only the total work done but also each separate piece orjob.

\Vith the above and other objects in view this invention has particularrelation to certain novel features of construction, operation andarrangement of parts, an example of which is given in this specificationand illustrated in the accompanying drawings, wherein Figure 1 is a sideview of the device. 7

Figure 2 is a fragmentarv transverse sec tional view, taken on the line2--2 of Figure 1.

Figures 3 and 4 show plan and edge views, respectively, of a star wheelema plo ed.

1* igure 5 shows an edge view of a counting disc employed, and

Figures 6 and 7 show the respective side views of said disc.

Referring now more particularly to the drawings, the numeral 1designates a frame designed to be attached iii any suitable manner to asewing machine. The numeral 2 designates a fragmentary part of theneedle holder which reciprocutes up and down as the machine operates.Pivotally mounted within the casing there is a rocker 3 whose respectiveends have deep sockets forming bearings for the rods 4 and said rockerand rods forming an extensible lever. The numeral 6 refers to adepending guide which is fastened to the frame I and in which theactuating ha r T reciprocate The lower end of the bar 7 rests on theneedle holder .2 and is held in conta t therewith by means of the pullspring 8. one end of which is connected to the casing and the other endof which is attached to the yoke 9, hereinafter referred to.

Attached to and depending within the frame there is a track 10 on whichthe yoke 9 reciprocates. The outer ends of the rods 4 and 5 are pivotedto the bar 7 and the yoke 9. respectively, and-the yoke is therebyreciprocated as the needle holder reciprocates up and down.

The numeral 11 designates a counting machine as a whole. The mechanismof this machine is similar, in principle, to the ordinary speedometerand it will not be described in detail. It is provided to register thenumber of yards of work done, both the total yardage and the yardage ofeach piece of Work. It embodies'a main shaft 12, and a. drive shaft 12'which is aligned therewith and one end of which is formed with a wrist13. Connected to this wrist, at one end, there is a connecting rod 14whose other end is pivoted to the yoke 9. The shaft 12 also has theusual fly wheel 15 fixed thereon, for the well known purpose.

The counting discs of the machine 11 are mounted on the shaft 12 and areoperated therefrom in the well known manner.

The counting discs 16, 17 and 18 register the ardage of each piece ofwork from onetentli of a yard to one hundred yards and at any time maybe set at zero in the usual and well known manner.

The discs from 19 to 23, inclusive, register the total measurement.Ordinary hemstitching runs thirty-two stitches to one.- tenth of a yardand the shaft 12 is geared to the drive shaft through reduction gears24, and 2G to give the proper rate of rotation to the main shaft and thecounting discs thereon.

\Vhat I claim is:

1. The combination with a sewing ma' chine having a reciprocable needleholder. of a registering mechanism including a frame adapted to be.secured to the arm of the machine, a main shaft rotatably mounted in theframe. counting discs mounted on said shaft and operated therefrom. aguide carried by the frame, a bar rcciprocahhin the guide. and operatedby the needle holder. a rocking lever, a reciprocating \'okc mounted inthe frame, said lever being pivoted at its rcspcc tivc ends to the barand yoke. a drive shaft formed with a wrist, a connecting rod con- Ill)necting said yoke to the drive shaft wrist, a gearin operativelyconnecting said shafts.

2. T e combination with a sewing machine having a reciprocable needleholder, of a registering mechanism including a frame adapted to besecured to the arm of the machine, a main shaft rotatably mounted in theframe, counting discs mounted on said shaft and operated therefrom, auide carried by the frame. a bar reciproca 1e in the guide, and operatedby the needle holder, a rocking lever. a reciprocating yoke mounted inthe frame. said lever being pivoted at its respective ends to the barand yoke, a drive shaft formed with a wrist. a gearing operativelyconnecting said shafts, said rocking lever bein, lengthwise adjustable.

3. The combination with a sewing machine haring a reciprocable needleholder, of a registering mechanism including a frame adapted t0- besecured to the arm of the machine, a main shaft rotatably mounted in theframe, registering discs Operatively connected therewith, and actuatedtherefrom, a guide carried by the frame, a bar reciproca le in the guideand operated by the needle holder, 3. reciprocatingyoke carried by theframe, a rocking leyer mounted in the frame and pivoted at one end tosaid bar and at the other end to said yoke, a pull spring connected atone end to the frame and at the other end to the yoke and operating tohold said bar in contact with said needle holder. a drive shaft formedwith a wrist, a connecting rod connecting said yoke with said wrist andgearing operatirely connecting said shafts.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
